To aZZ'whom it may concern: p Y

Be it known that I, JoNns H. PARKER, .a citizen of the United States,and a resident of the city of St. Louis and State'of Missouri, haveinvented a new and useful Improvement in Reversible Windows, of whichthe following is a specification.

My invention relates to reversible window constructions, and has for itsprincipal objects to provide a reversible-window construction which canbe applied in lieu of the ordinary giindow construction in commonuscwithout war appearance of the window sash or frame, to detachablymount the window-sash u on the cord-attaching blocks, to im rove t econstruction of the cord-attaching bi to improve the means formanipulating the guide-strips, to provide means for locking theguide-strips either when retracted or when moved out into efiectiveposition, to generally simplify, chea en, and improve the constructionof reversib e windows, and other objects hereinafter more fullyappearing.

. The invention consists in the parts and in the arrangements andcombinations of parts hereinafter described and claimed.

In'the accompanying drawings, forming part of this specification, andwherein like symbols refer to like parts wherever they occur, Figure 1is a front view of a portion of a window, parts being shown in section.Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is asectional view on the line 3 3 of Fig. .1. Fig. 4 is a detailperspective view of a portion of the pulley-stile, showing thecord-attaching block for the upper sash in position. Fig. 5 is a detailpers ective view of a fragment of the window-sas showing-a pintle andthe guide-strip in its extended or effective position.

The frame for my improved window may be of the same construction as thatordinarily used, except that the pulley-stiles 1 are not provided withthe usual parting beads or strips which guide the sashes and formgrooves in which the sashes move. Instead the pulley-stiles are fiat andare provided with grooves 2 to receive the cord-attaching blocks, uponwhich the sashes are su ported, and grooves 3 to receive the gui-str1ps, which are movably mounted on the sashes. A cord-attaching-blockgroove 2 and a guidestri groove 3 are provided for both the upper andlower sashes, the equipment'of the two sashes being similar. Each sashis thick enou 'h to cover both of its respective grooves 2 an 3, asshown in Figs. 1 and 3, and fits snu ly between the pulley-stiles. 4

Tie preferred form of cord-attaching block 4 is made of sheet metal, itslower port1onbeing box-shaped,'as shown in Figs. 3'and 6, the 1 up erportion 5 being formed with prongs 6 an turned over the end of thesash-cord 7 to firmly secure the cord-attaching block thereto. The fulllength of sash-cords, counterbalance-weights, and pulleys are not shown,7 asthey are of the ordinary construction.

A horizontal slot 8 is formed in the side of the cord-attaching blocktoward the inside of the wihdow, said slot 8 connecting with a I}bayonet-slot 9 in the side of the block adj acent to the window-sash.

The window-sashes 10 are rovided at to enter through the slot 8 and restin s 0t 3 of the cord-attaching block. To permit the insertion of thesashes with their pintles, a horizontal groove 12 is provided in thefaces of the pulley-stiles 1. The oove 12 extends from the'front of thesti e to the cordattachi'ng-block groove for the u per sash. Thesegrooves are arranged near t e middle of the lpulley-stiles, and hence asingle groove mo in eac stile suffices for the insertion of both theupper and lower sashes. To insert a sash, ltSTGSPGCtiVG cord-attachingblocks are ulled down until the horizontal slots 8 reglster with-thegrooves 12 in the stiles. Then :05

the pintles 11 are (passed alon the grooves 12 and into the cor-attaching looks.

The window-sashes" are provided with vereach side with a pintle 11, whicis ada ted a littlev greater thania-semicircle.

tical grooves 13 for. the guide-strips, which will register with thegrooves 3 in t epulleystiles when the sashes have their pintles mountedin the cord-attaching blocks and are turned into the vertical position.Guidestrips 14 are movably mounted on the window-sashes in said grooves13. The guidestrips are provided at their inner edges,- near I theirupper and lower ends, with recesses 15,

having circular walls with an angular extent Near the top=of the sashailink 16 is pivoted, which has a cylindrical head 17 fitting in therecess at I the upper end of the guide-stri Near the bottom ofthe-sash'a bell-cran lever 18 is pivoted, which has-a cylindrical head19 fitting in the recess at-the lower end of the guide -str%p.

ivotally mounted on the end of the bellcrank lever 18 opposite the head19 is-an ad- I justablesecuringblock 20, preferably made of sheet metaland formed in one piece. As

shown more clearly in .Fig. 14, the block 20 --is substantially U shaed, thereby providing overlapping ears 21, w ich are perforated for thereception of pivot-pins 22, and. is formed with upturned lugs 23, whoselower edges 24 are beveled to engage serrations or teeth 25 on the outerends of connecting-links 26. The block 20 is locked in its adjustedposition on the link 26 by a set-screw 27,- which impinges against thelink and forces its serrated edge into intimate engagement with thebeveled lugs on the block.

The links 26 are formed with perforated lugs or ears 28, which arepivotally connected to a bell-crank operating-lever 29, preferably madeof-sheet metal and formed in one piece with the oppositely-disposedoverlapping ears 30, having perforations which reglster with likeerforations in the body por tion of said be l-crank lever for thereception of pivot-pins 31. The lever 29 is provided with a square 0ening 32 for the passage of a squared shan of a spindle 33. The spindleis mounted in the lower portion of t e window-sash, about the centerthereof,

and has for its bearing a cylindrical portion 34, which is seated in asuitable recess in the sash. The spindle also has a shouldered collar35, which has a bearing in a countersunk escutcheon 36. i

The end of the spindle Within the escutcheon is squared, as at 37, toreceive a suitable key (not shown) having a complementary recess orpocket, whereby the spindle and bell-crank lever may be turned, and,through the medium of the herein-described connections and levers 18,the guide-strips at both sides of the sash are simultaneously movedin orout. When moved outwardly,

.the-guide-stri s extend to the bottom of the grooves 3 in t eulley-stiles and lie partly in thegrooves in t esash, as shown in. Fig.3. When retracted, the guide-strips lie entirely sse,251

within the grooves in the sash, and the sash is then free to turn on itspintles in the cord attaching blocks.

The arrangement of the bell-crank lever 29 and connectmg-links 26 servesnot only as a means for manipulating the guide-strips, but

also serves as an automatic locking means at either extremity of itsmovement.

In Fig. 9 the parts are shown in the position they assume whentheguide-strips are moved outwardly. When in this osition, ,the entiremanipulating mechanism is locked and prevented from being moved except.

upon the proper rotation of the bell-crank lever by applying a suitablekey to the square end of the spindle. By turning the bellcrank lever inthe direction indicated by the arrows the. arts will be moved into theposition. shown in Fig. 10, when the uide-strips will be retracted andthe parts loc ked, exce t that areverse movement be imparted to t ebell-crank lever. the manipulating mechanism at eachextremity of itsmovement. This locking means is desirable, as it insures the holding ofthe guide-strips in either their retracted or outermost posltions. Thelocking is performed automatically, the operator merely insertin the keyand turning the operating-lever unti it stops at the limit of itsmovement. When the window is entirely equipped, practically none of. themechanism is visible from the Thus a lock is provided for outside exceptthe escutcheon for the keyhole, which may be ornamental.

Obviously my device is ca able of considerable modification within tescope of my invention, and therefore I do not wish to be limited to thespecific construction shown and described.

What I claimas m invention, and desire to secure by Letters atom, is
